Description Task-directed vision obviates the need for general image comprehension by focusing attention only on features which contribute useful information to the task at hand. Window-based visual tracking has helped make long strides in research along this paradigm as motion tracking becomes a problem of local search in a small image region. While the gains in speed from such methods allow for real-time feature tracking on off-the-shelf hardware, they lose robustness by giving up a more global perspective: Window-based feature trackers are prone to such problems as distraction, illumination changes, fast features, and so forth. We apply sensor fusion techniques to "tracker fusion," where multiple trackers simultaneously track the same feature while watching for various problematic circumstances and combine their estimates in a meaningful way. By categorizing different situations in which mistracking occurs, finding appropriate trackers to deal with each such situation, and fusing the resulting ...
